iLAMP BURNER AND FofNT.'

SPECI ICATION forming part of Letters Patent N o. 728,080," dated May 12, 1903.

' Application filed July 8, 1902. Serial No. 114,7Q8. (No model.) l l l To @ZZ whom itv may concern.-

Be it known that I, GEORGE T. BROWN, of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Lamp Burners andl Fonts; and I hereby declare that the following is a full, clear, and exact description thereof, referenc-e bein g had to the accompanying drawings, which form part of this specification.

This invention is an improvement in burn- 'ers and fonts for lamps, lanterns, dac.; and its objects are, rst, to produce a burner of very simple construction, the parts of which can be readily assembled and securely connected without solder; second, to make a slip-joint connection between burner and font collar or nipple and to utilize the wick-raiser rod as a means for preventing rotation of burner on font third, lto utilize the wickraiser rod as a means for supporting and holding the wick-tube in position in the burner; fourth, to utilize the air-chamber ring of the burner as a means for securing the wick-tube support or nipple securely to the font and' to also utilize this ring as'the chimney or globe support or connection, and, iinally, to construct thevburner vso that the wick-tube will hold securely in its proper position within the burner without using a bottom plate to hold itin position, as is usual, and thus providing a recessed burner open at the bottom, enabling it to be slipped on or fastened tothe outside of the font-collar.

With these ends in view the invention consists in the novel constructions and combinations of parts summarized in the claims following the detailed description of the inven-.

tion, as illustrated in the accompanying drawings, in which- Figure 1 is a sectional elevation through the complete burner, the latter beingv provided with chimney-engaging fingers. Figl 2 is a side view thereof." Fig. 3`isa horizontal section through Fig. 1. Fig. liis a detail view of a slight modification of wick-tube. Fig. 5 is a detail sectional view of the `font collar or nipple. Fig. 6 is a detail enlarged Vertical section of a slight modification. Figs. 7 and 8 are detail side and sectional views of a tail sectional view showing anair-cap on the burner.

ferred form incertain cases. Fig. 11 isa de- The font 1 may be of any sui-table constrnc- 55 tion and provided with a collar 2 for thev attachment of the nipple of the burner. In the preferred construction this collar instead of being threaded, as it usually is, is plain iinished, and the burner-nipple 3 is adapted 6o to be slipped or telescoped therewith instead of being screwed thereto, it beingpreferably formed to slip over the collar. lhe collar, moreover,:is provided with opposite Vertical slots Qa'for the accommodation of the wick- 65 raiser rod 5,;which slots and rod not only prevent the burner casually turning on the plain collar, but also4 insure the proper registration ofthe Iwick-tubewith the combustion plate or hood of the'burner.

The burner-nipple 3is preferably drawn from one piece of metal and is shaped to properly engage with and fit the collar, preferably slipping over the latter, `as indicated in Figs. 1 and 3. top of the nipple is a wick-tube 4., which may be drawn or bent into`proper shape to receive and guide thewick.V The top of the nipple Extending centrally through the is suitably apertnred for the passage of the wick-tube, and the tube should not have any 8o lateral play in the aperture.- ISaid tube is upheld in position and in the nipple by the wick-raiser ro'd 5, which passes through the nipple, transfixing the opposite walls thereof,

and lies close against the Wick-tube and is connected therewith, as and forv the purposes hereinaftervspecified.

In Figs. 1 and 3 the wick-raiser rod 5 has but one star-wheel 5a, which engages the wick through anl opening 4b in the Vwick-tube. Fig. 4. two star-wheels ,prare' shown on the rod, and the tube is correspondingly apertured. The wick-raiser rod may be connected to the wick-tube by passing it through .eyes

In 9o 4a, struck up from the metal of the wick-tube, 95

as indicated in Figs. l, 3, and 6. In Fig; 4 a

single eye 4.@ is shown between the star-wheels, through which eye the wick-raiser rod passes. Instead of striking up eyes la or 4 from the wick-tube ears 4t may be struck up therefrom xoo at opposite sides of the star-wheel opening, as in Figs. 7 and 8, said ears being tran'sfxed by the rod 5 and performing the same office as eyes 4a. Figs. 9 and lO show a very useful and preferable construction if the tube is not of sufficient thickness or ductility to permit eyes to be struck up therefrom,a U-shaped yoke 4J being placed against the Wick-tube with its ends projecting in front thereof and forming eyes which are transfixed by rod 5, so as to hold the wick-tube in place. In this construction the wick-tube may be beaded above the nipple and below the yoke, as at 4f 4g, to prevent vertical displacement of the tube. In all these constructions, however, the wick-tube is firmly held and centered in position within the nipple by the slot in top of nipple, the wick-wheel, and the wick-raiser rod 5, which latter serves the double purpose of raising the wick and locking the wick-tube in position within the nipple, enabling soldering to be dispensed with. These several modifications show how the wick-tube can be fastened and supported in place Within the nipple by the wick-raiser rod in various ways, so that soldering may be dispensed with, and I do not wish to limit myself to any particular connection between wick-tube and wickraiser rod to accomplish this purpose.

In Fig. 6 I have indicated how the nipple might be threaded to screw onto a collar; but this threaded connection is quite old and is not claimed herein.

In Fig. llI have shown a burner similar to that shown in Figs. 9 and 10, with an air-cap 8 attached to its top for the purpose of conducting air to the top of wick-tubeand producing a better iiame. Such air-caps are old and are not specifically claimed herein. They perform the same office as cap 6b in Fig. 1- to wit, increase the brilliancy of the flameand they may be readily att-ached to any of the burners shown.

NVhen the nipple is slipped onto the collar, the projecting ends of rod 5 engage slots 2a and prevent the burner turning. Vhen applied to lamps, the slots 2a may have horizontal extensions 2"'at bottom, as indicated in Fig. 5, so that after the nipple is slipped on the collar it can be slightly turned thereon, so as to engage rod 5 with the portions 2b of the slots and lock the nipple on the collar; but when used with chimney or globe burners I prefer to make the slots 2a straight and vertical, so that the wick-raiser rod when engaged therewith will keep the burner in proper position and prevent rotation thereof. In such cases suitable means should be provided for holding the nipple down on the collar, and this may be readily accomplished by utilizing the combustion or air chamber of the burner, as indicated in the drawings. In Fig. 1 the font has an annular shoulder ln exterior to and larger than the collar and adapted to be engaged by an annular perforated rng b, forming the outer wall of the air-chamber of the burner. This shoulder l I consider a very useful and novel feature, as it aiords a simple and efficient means for centering and retaining the burner on the font in connection with the ring 6 and devices hereinafter described. On this ring is supported the perforated cap 6 and flameguard 6b, of usual or other suitable construction, and this ring may also be provided at top with any suitable engaging or retaining devices to connect a globe or chimney with the burner, as desired. The burner is shown as provided with chimneyengaging fingers Gc; but the particuluar kind of engaging devices is immaterial and can be varied to suit the use or purpose of the lamp or lantern for which the burner is designed.

The ring 6 may be locked to the fontin any desired way, a simple and efficient means being shown in the drawings, such vmeans comprising pins or lugs 7a, projecting horizontally from the top of shoulder la and which may be conveniently formed by wires 7, placed on top of the font and suitably secured in place, as by passing them through eyes l", struck up from the metal of the top of font, as shown in Figs. 3 and 5, these wires being preferably arranged parallel with and on opposite sides of rod 5, as indicated in Fig. 3. The ring 6 is provided with inverted L-shaped slots Gd in its lower edge adapted to engage with lugs 7 when the ring is slipped onto the shoulder, and then by partially turning the ring it is locked to the font by lugs 7, entering the horizontal portions of slots 6d, as shown. The ring is also provided in its lower edge with slots Ge to accommodate the projecting end or ends of rod 5, as shown in the drawings. When the ring is in place, the slots 6c prevent the wick-raiser rod 5 rising, and con sequently the ring when in position and locked will hold the burner-nipple and wicktube firmly down upon the font-collar and maintain tight joints therebetween.

In some cases the chimney or globe supports might be directly connected to the nipple, as indicated at 9 in Fig. 7, and when the wick-rod 5 is locked to the collar by engaging the slots 2b, as described, the burner and chimney will be securely held to the font in a very simple manner.

I do not wish to restrict myself to the employment of the ring 6 nor the particular fastening means shown and refer to the appended claims for concise summaries of what I deem the essential features and combinations of parts for which I desire protection.

I-Iaving thus described my invention, what ICO IIO
